JB4 Logging, stacking and Map 6 Discussion

So map 1 on 91 I’m safe right? I shouldn’t need to log?

For the e30 I need to do a log with map 2 correct? And then move the settings over to map 6 and make the small changes? Still learning.
Map 2 might be to much for stock clutch down low, start with this.

1500 0
2000 1.5
2500 2
3000 2.5
3500 3
4000 3.5
4500 4.5
5000 5.5
5500 6
6000 6
6500 5.5
7000 5

As a person that's played with this, I'm not sure it's worth it. The factory boost curve is already biased towards low end power. Consider keeping your current maps 6 that you're happy with, and adding some sort a pedal tuner like BMS sells.
For me the pedal tuner was a very worthwhile upgrade. Really added to the driving experience in a great way.
 
Thank you to all the contributors to this thread! Very informative. We are going to be testing our upgraded turbos on a Mk7.5r Golf R car with the JB4 and the insights here are going to save us a lot of time dialing it in and troubleshooting. It will be interesting to push the limits of what this piggyback controller can do when paired to stock ECU programming.

So if I’m on map 1 and I’m tired of wheel spinning in 1st gear if I adjust the user settings to limit boost to 20 psi will that take affect when I save it because it says map 6 at top but I’m on map 1? Just learning how to tweak things slowly wish I had a user in Modesto CA that could help

If you running the newer firmware found in post 1 here: https://www.n54tech.com/forums/showthread.php?t=50428 the way the boost per gear works is the value you put in is the amount of psi it will cut. It can pull it lower than stock boost levels. The only setting that is map 6 related is the boost chart. The rest of the settings in the user adjustment section are global and affect all the maps. If you not running one of the newer firmware versions released in 2019 and its something older post your firmware version and I can let you know how to adjust it.

Awesome I’m on the newest map, so if I put in 20 on the limit it won’t go past 20psi in first? or do I need to put in -5 or something It sound like you are saying the value I put in will subtract from so my max boost is 24 and i put in say -8 so my max boost is 16 psi on first gear? Everything is a little bit confusing obviously there is a lot to learn.

You need to put in a positive value of what you want it to cut in first. So if you make max boost 1st 6 it will cut 6psi in first. If you put 2 it will cut 2. If you put 8 it will most likely pull it below stock. At a certain point the ECU will get unhappy and throw a overboost code if the cut is too high.

Ok that makes perfect sense awesome!

OK, I was playing with Map 6 and was able to get the trim to a max 42.

3rd gear pull also :) ive been reading learning learning learning..

1500 16
2000 17
2500 18
3000 18.5
3500 19
4000 21

Yes I have considered that. Im just waiting and hoping that George comes up with an algorithm to correct the pedal lag.

That leads to my next question. I just downloaded the newest firmware a couple of days ago. Did some driving but not sure of the difference. Has anyone downloaded:
FIRMWARE RELEASED 01/27/2020, LINKED TO THIS POST

Firmware version is 60/86/5 - File Name JB4_EA888_8_6.hex



If so any noticeable change? Maybe George can jump in. I would like more explanation as to what I should notice with;
Refined part throttle driving
Change in spool up speed

Logging resolution increased

Thanks

New firmware prevents autoclear cat codes.
This is the only reason I am keeping my current firmware. The auto clear of the o2 codes works 95% of the time. About once every 2 months a cel will slip through and I'll have to manually clear it, but that's after it has auto cleared almost daily. Wife would go ballistic if the light stayed on all the time. She already thinks I'm destroying the car instead of upgrading like I keep telling her. Lol.

installed the hybrid last night, ran it on map 1, checked logs, then went map3 checked logs and created initial base Map 6 setting as below for test and run.
just talked to George about them today and ill be added some request after 5k and will run some more logs tonight... this is still on e3blend.

whats crazy feeling is how much faster the car feels from the added volume of the bigger turbo will still at the same boost levels of the is20 (except after 5800rpm)

1500-1
2000-2
2500-3
3000-3.5
3500-4
4000-5
4500-5
5000-5
5500-6
6000-6

got it used from a local member here in Vegas, 034 tunes it very mild....loba (the company they partner with for the turbo) has done 450+ With it on pump.
he ran it for 4k and decided it was not enough so he pulled it and had the motor build and went EQT xl - doing low 500 on 91, and highs on full e85. I rode in it on 91 and holy SHIT it goes !

I did the same for so long I thought it would never update to new firmware. Wanted to experiment and take advantage of some features with new F/W. So bit the nipple and took the plunge. Sure enough, CEL. Installed Vibrant straight spacer with medium insert and no light since. MAp 3 is nice in warm weather. Worth it.
